MOST ACCURATE FORECAST: Slight chance of overnight storms in the Valley

Posted
and last updated

PHOENIX — So far, the Valley has caught a break from storms to start the workweek, but there is a slight chance of a few storms moving in overnight.

The Valley is also under an Ozone High Pollution Advisory through Wednesday.

Kids, older adults and people with respiratory conditions, like asthma or COPD, should limit time outside during the day or breathing may be difficult.

Monsoon storms will be developing in the higher terrain in the heat of the day. Then, there's a chance some of that action could move into the Valley from the north or east in the late afternoon or evening.

A disturbance moving through northern Mexico will enhance our monsoon storm potential even more for the rest of the week and into the weekend.

Valley storm chances will increase to 60 percent by Friday and Saturday.

Any storms that develop could bring heavy downpours and flooding. So, stay tuned for updates as we get closer.

Those higher storm chances will help drop temperatures. Look for highs in the 90s across the Valley by Friday and over the weekend.
